23 microns

Robin Leadbeater

The slit is 23 microns or 3 arcsec. It normally runs in the Dec direction which is probably the best bet as the star and PSN will lie at different positions along the slit provided the seeing and guiding is good enough to split them. I could just pick up a weak spectrum of the pair with perhaps signs of a broad H alpha emission line  which would indicate a type II, though there is quit a bit of that around in the galaxy background as well. No split though (and to be honest at mag 17.9 I would not stand much of a chance of getting a useable spectrum in any case)
